. DISPENSING CLOSURE FOR BOTTLES AND THEQLIKE,

Application filed May 25, 1927, Serial No.

My invention relates to dispensing clo-- sures for bottles and other hollow vessels such as are used for perfumes, cosmetic liquids and the like, and has for itsobject to provide an improved closure of simple con-- with a flat member surrounding the projection and adapted to bear against the cap. Central openings are provided in the cap and cover in registry with eachother for the passage of the material to be dispensed. One of the two arms of the bell-crank lever is provided with a hole for the reception of a pivot which extends outwardly from the cap, and the other arm has a hole for the reception of a pivot which extends inwardly from the cover, so that when the cover is rotated the projection on the bell-crank lever is turned to open and close the discharge 3o openings in the cover and cap.

A form of embodiment of the invention is illustrated by way of example in the accompanying drawing.

Fig. 1 is a sectional View of the cap,

Fig. 2 is a plan view of the same,

Fig. 3 is a sectional view of the cover,

Fig. 10 is a sectional view of the closure when in closed position, and

Fig. 11 is a plan view of the same.

The closure comprises a cap A adapted to fit over the neck of a bottle or the like, a cover B rotatably fitted over said cap, and a closing member C interposed between the cap and the cover. The cap A is provided with a. peripheral boss g, and with a de- 193,996, and in Germany February 6, 1926'.

The cover B is also provided with a central discharge opening 9, the edges of which are pressed inwardly into a frusto-conical shape and thus suitably stifiened. The cover B also has a pivot member h, spaced from the central discharge opening 9 and formed by stamping or pressing the material of the cover inwardly The closing member C, as shown in Fig. 5, is shaped like a bell-crank lever and has at the intersection of its two arms an outwardly extending hemispherical projection z and an offset annulus 7c surrounding said projection. In one arm of the bell-crank lever is formed a hole Z adapted to receive the pivot member 65, and in the other arm is formed a. larger hole m adapted to loosely receive the pivot member h, for a. purpose to be described.

The closing member 0 is rotatably sup ported by means of the hole Z on the pivot B in such a manner that the annulus is engages and registers with the annulus 7 when the closure is in closed position. The pivot member 72. of the cover rests loosely in the larger hole at of the closing member C. The edge 77 of the cover B is turned downwardly and inwardly over the peripheral boss 9 of cap A so as to rotatably secure the cover to the cap.

The operation of the device is as follows. When cover B is rotated in the counterclockwise direction the closing member C will be turned to the open or dispensing position shown in Figs. 8 and 9, whereupon the contents of the vessel may pass out through the openings e and 9. When it is desired to bring the closure to the closed position shown in Figs. 10 and 11, the cover B is rotated in the clockwise direction, whereupon the closing member C will be turned by the pivot h of said cover, the loose fit of the pivot in the hole m being provided to permit this action. Thus the hemispherical projection z' of the closing member 0 will be moved until its seats in the discharge opening 9 of the cover, the cam action of projection 5 against the frusto-conical edge of opening g causing the cover B to raise in such a manner that it is elastically deformed and presses the annulus is tightly against the similar annulus f, thereby tightly closing the discharge hole 6.

I claim: i

1. A dispensing closure for bottles and the like comprising an apertured cap adapted to fit over the mouth of a bottle, a cover rotatably secured to said cap and having a discharge opening registering with the aperture in said cap, the edges of said opening being turned inwardly, and a closure member interposed between said cap and said cover and pivoted to said cap, said closure member being provided with a projection constructed and arranged to seat in said opening and being provided with a portion adapted to close the aperture in said cap;

2. A dispensing closure for bottles and the like comprising an apertured cap adapted to fit over the mouth of a bottle, a cover and being adapted to close the aperture in said cap when moved to closedposition.

In testimony whereof I have affixed my signature.
